TLDR: Currently the Discovery Sphere and Hyperion Matrix don't unlock for the Thalan. The universal soil adaptor unlocks with Habitat Improvement instead of Universal Soil Adaptation.
Also, the Antimatter Containment tech currently does nothing.

The prerequisite for the Hyperion Matrix is still listed as "StelllarCartography", which is a tech the Thalans don't have. The proper prerequisite is "HyperionMatrixTech"

Here the problem is that the generic name is "ResearchMatrix". It should be "ResearchMatrixTech".

-------------------------------------------------------------------
Here the problem is that the prerequisite for the universal soil adaptor is "HabitatImprovement" when it should be "UniversalSoilAdaptation".
--------------------------------------------------------------------
As for the Antimatter Containment tech that currently does nothing the problem seems to be that there isn't currently a 1 per colony +4 manufacturing adjacency bonus building to go between the +5 quantum power plant and the +3 Fusion power plant so the tech no longer has a function.
It used to unlock the anti matter power plant but that was moved to Industrialization adaptation and had its function changed.
Edit: My first solution to the discovery sphere bug broke it for everyone else. I edited in the correct fix.
